Where civilians are employed in an ATC tower they generally undertake the same duties as the blue suiters. They hold either civil servant grade E1 or E2. the E2 man the Visual Control Room, Duty driver, Switchboard Operator. The E1 is a Cpl equivelant so they undertake runway control duties and watch I/c duties in addition. Out of interest they also have civil servant AVO's who undertake contolling duties.
